Loud noise/pop when powering MiniFreak

When I power-up my MiniFreak, I get a loud pop, both on the audio outputs as on the headphones.

Especially on the headphones this is painfull. Turning down the master volume, does not solve this.

The noise is so loud, I am scared it will damage my headphone, mixer, amplifier and speakers, and last but not least, my hearing!

As a side effect, I’m a little less eager to play with my beloved Freak :disappointed_relieved:

I’ve just sent in a Support Request through the website. But I’m wondering if more people have this issue.

Is the sound from the Minifreak or the power adapter/socket?

Have you tried powering up in a different socket - maybe even in another room?

HI @frodi

I’m going to assume that you mean the pop sound isn’t physically coming out of the MiniFreak casing itself, rather it’s a signal coming from its audio outs?

Might seem like a daft question, but it’s just to clarify.

If that’s the case, generally it’s a good idea to lower any audio inputs on your system that the MF is connected to BEFORE you power it up, in fact it’s generally a good idea to power up any external sound generating kit before powering up anything which amplifies and makes actual sound.

I have a powering up routine i use, which i picked up when working in TV many years ago, EVERY PA and studio engineer i’ve ever worked with use it too.

When powering up, power up from physical instruments first, such as your MF and then your mixer (if you use one), then your computer.
Once your computer and interface are fully powered up, then power up you amplifier/monitor speakers.
When you power down, do it in the exact reverse order and make sure your monitor speakers/amp is turned all the way down before you turn it off too. that ‘volume’ knobs/faders etc are all the way down first!
This is precisely to avoid what you’ve just described in your first post, assuming that it’s signal related and not an acoustic noise coming from your MF.
If you use a patch bay to patch in things like preamps, make sure they are disconnected or power up anything that might be routed to your interface through them first, such as mic preamps/compressors etc if you’re using them in that session.
If you use a patch bay and want to power something up connected to it after your computer is fired up, disconnect it from the patch bay first, then power it up and reconnect it to the patch bay.

If it IS a noise coming from the MF hardware, then if it’s still under guarantee you should return it to where you purchased it from. If not, get a qualified engineer to check it over.
I’m fairly sure you mean it’s signal related though.

This is something EVERYONE should be doing anyway to protect your equipment and, more importantly, your hearing.

HTH!

yes, it’s noise coming via the audio cable connections. Both the TS plugs and the headphone out.

I usually perform a power-up sequence, starting with the synths, followed by the mixer and finally the amplifier.

But if I’m using the MF with only a headphone, I tend to leave the headphone plugged.

I now know, to connect the headphone after I’ve powered the MF.
My other synths can be used without me having to worry about the headphone connected during power-up or down. I guess it’s a MF thingy, I needed to get used to.

Thanks for the replies!

No mate, potentially it’s ANY powered piece of equipment and you SHOULD keep this in mind, ignore at your own peril… I’ve lost count of the people who ignore this that end up with rather expensive repair or replacement bills…
